Since the 1970s, due to the harsh natural environment encountered in pipeline construction, stricter requirements have been placed on the performance of the anti-corrosion coating. Therefore, in the research of pipeline anticorrosion materials, vigorously develop composite materials or composite structures, emphasizing that the anticorrosion layer must have good dielectric properties, physical properties, stable chemical properties […]

Stainless steel pipe is a kind of hollow long strip steel with light weight and high torsional strength, so it is widely used in petrochemical, food processing, medical light industry and other industries, and some machinery manufacturing industries also have certain applications. Nowadays, there are more and more choices of stainless steel pipes on the

Stainless steel pipe is mainly used for three purposes:

API 5L generally refers to the executive standard of pipeline steel pipe. Pipeline steel pipe is used to transport oil, steam, water, etc. extracted from the ground to oil and gas industrial enterprises. Pipeline steel pipes include seamless steel pipes and welded steel pipes. At present, the commonly used welded steel pipe types on oil

Welding is an important link in stainless steel pipe processing and has a wide range of applications in many fields. Only by ensuring the quality of the product can the safety of the product be improved. However, welding defects are extremely unfavorable factors in production, and stainless steel pipe cracks are a common and very

①. No matter what steel pipe is carbon steel pipe, it is just that the carbon content of different specifications of steel pipe is different, and whether other trace elements are added to form a steel pipe with special performance, such as: stainless steel pipe ②. Ordinary carbon steel pipes are very easy to rust

The relevant content of pressure steel pipe testing is introduced here. If you have actual testing needs, it is recommended to send it to a professional third-party testing organization Huajin for testing. Huajin Testing has very rich relevant testing experience, professional technical teams and laboratories. , Can quickly issue a rigorous and true test report.

Galvanized steel pipes are divided into cold-galvanized steel pipes and hot-dip galvanized steel pipes. Cold-galvanized steel pipes have been banned, and the latter has been advocated by the state to be temporarily usable. In the 1960s and 1970s, developed countries in the world began to develop new pipes and gradually banned galvanized pipes. Four ministries

Threaded seamless steel pipe is a kind of seamless steel pipe made by special process. It has excellent strength and toughness, good corrosion resistance, and is suitable for various pipe connections.1: Screw thread seamless steel pipe Introduction Screw thread seamless steel pipe is a jointless pipe made of high-quality and high-purity raw materials. It is

Boiler tubes refer to steel products that are open at both ends and have a hollow section. The ratio of its length to the surrounding area is large. According to the production method, it can be divided into seamless steel tubes and welded steel tubes. Wall thickness indicates a wide range of sizes, from capillary
